BACKGROUND: Anterior cruciate ligament (ACL) injury is known to have a number of deleterious effects on lower limb muscle function. Alterations in muscle size are one such effect that have implications towards reductions in strength and functioning of the lower limbs. However, a comprehensive analysis of alterations in muscle size has yet to be undertaken. OBJECTIVE: To systematically review the evidence investigating lower limb muscle size in ACL injured limbs...

BACKGROUND: Monitoring resistance training has a range of unique difficulties due to differences in physical characteristics and capacity between athletes, and the indoor environment in which it often occurs. Traditionally, methods such as volume load have been used, but these have inherent flaws. In recent times, numerous portable and affordable devices have been made available that purport to accurately and reliably measure kinetic and kinematic outputs, potentially offering practitioners a means of measuring resistance training loads with confidence...

BACKGROUND: Stretching a muscle not only increases the extensibility or range of motion (ROM) of the stretched muscle or joint but there is growing evidence of increased ROM of contralateral and other non-local muscles and joints. OBJECTIVE: The objective of this meta-analysis was to quantify crossover or non-local changes in passive ROM following an acute bout of unilateral stretching and to examine potential dose-response relations. METHODS: Eleven studies involving 14 independent measures met the inclusion criteria...

Every women's and men's world records from 5 km to the marathon has been broken since the introduction of carbon fibre plate (CFP) shoes in 2016. This step-wise increase in performance coincides with recent advancements in shoe technology that increase the elastic properties of the shoe thereby reducing the energy cost of running. The latest CFP shoes are acknowledged to increase running economy by more than 4%, corresponding to a greater than 2% improvement in performance/run time. The recently modified rules governing competition shoes for elite athletes, announced by World Athletics, that includes sole thickness must not exceed 40 mm and must not contain more than one rigid embedded plate, appear contrary to the true essence and credibility of sport as access to this performance-defining technology becomes the primary differentiator of sporting performance in elite athletes...

BACKGROUND: The World Health Organization launched the Global Action Plan for Physical Activity (GAPPA) in 2018, which set a global target of a 15% relative reduction in the prevalence of physical inactivity by 2030. This target, however, could be acheived in various ways. METHODS: We use an established multi-state life table model to estimate the health and economic gains that would accrue over the lifetime of the 2011 New Zealand population if the GAPPA target was met under two different approaches: (1) an equal shift approach where physical activity increases by the same absolute amount for everyone; (2) a proportional shift approach where physical activity increases proportionally to current activity levels...

REVIEW
Kate E Webster
While there has been significant interest in the documentation of return to sport outcomes following anterior cruciate ligament (ACL) injury, the elite level female athlete has not been a focus of this research. This is despite women being at increased risk for ACL injury and considerable global growth in women participating in sport. Therefore, the focus of this review was to examine the available literature regarding return to sport outcomes in elite level women with an ACL injury. The topics of discussion focus on return to sport rates, timing and determinants of return to sport, longevity of play, return to sport performance, and further ACL injury...

REVIEW
Ryo Kataoka, Ecaterina Vasenina, Jeremy Loenneke, Samuel L Buckner
Over the past several decades, periodization has been widely accepted as the gold standard of training theory. Within the literature, there are numerous definitions for periodization, which makes it difficult to study. When examining the proposed definitions and related studies on periodization, problems arise in the following domains: (1) periodization has been proposed to serve as the macro-management of the training process concerning the annual plan, yet research on long-term effects is scarce; (2) periodization and programming are being used interchangeably in research; and (3) training is not periodized alongside other stressors such as sport (i...

#14
Felipe C Vechin, Miguel S Conceição, Guilherme D Telles, Cleiton A Libardi, Carlos Ugrinowitsch
Previous research has suggested that concurrent training (CT) may attenuate resistance training (RT)-induced gains in muscle strength and mass, i.e.' the interference effect. In 2000, a seminal theoretical model indicated that the interference effect should occur when high-intensity interval training (HIIT) (repeated bouts at 95-100% of the aerobic power) and RT (multiple sets at ~ 10 repetition maximum;10 RM) were performed in the same training routine. However, there was a paucity of data regarding the likelihood of other HIIT-based CT protocols to induce the interference effect at the time...

BACKGROUND: Recent literature has identified that the vestibular system is often involved following a sport-related concussion. Furthermore, the consequences of vestibular and ocular/oculomotor involvement have been explored and identified as potential predictors for prolonged recovery. Although vestibular and ocular/oculomotor involvement is common following head injury, the clinical assessment strategies for vestibular function are less commonly practiced in the sports medicine setting and have limited research...

REVIEW
Judd T Kalkhoven, Mark L Watsford, Aaron J Coutts, W Brent Edwards, Franco M Impellizzeri
Causal pathways between training loads and the mechanisms of tissue damage and athletic injury are poorly understood. Here, the relation between specific training load measures and metrics, and causal pathways of gradual onset and traumatic injury are examined. Currently, a wide variety of internal and external training load measures and metrics exist, with many of these being commonly utilized to evaluate injury risk. These measures and metrics can conceptually be related to athletic injury through the mechanical load-response pathway, the psycho-physiological load-response pathway, or both...

BACKGROUND: The off-season period in soccer leads necessarily to changes in fitness status. However, there is a lack of systematization that allows identifying the magnitude of these changes in groups participating in off-season training programs compared with those subjected to training cessation. OBJECTIVE: This systematic review with meta-analysis was conducted to assess the effects of training cessation in off-season training programs on men soccer players' body fat, maximal oxygen uptake (VO2max ), yo-yo intermittent recovery test (YYIRT), vertical jump, sprinting time, and repeated-sprint ability...
